Build faster.
Or let me build it for you.

Every kit is a real, forkable codebase — not a template file or a tutorial. You get the full Next.js 15 source on App Router, TypeScript end-to-end, Tailwind CSS, Prisma schema and migrations, authentication wired with NextAuth or Clerk, role-based access, dark mode, SEO metadata and OpenGraph images, sitemap and robots configuration, plus deployment configs for Vercel, Cloudflare, and self-hosted Docker. SaaS kits add Stripe subscriptions with proration, webhook signing, team invites, audit logs, and admin panels with row-level permissions.

One-time purchase. Buy once, own it forever. There are no seat counts, no monthly fees, no licence audits, and no telemetry. You get the source code at the version you bought it, and any future updates we ship for that kit are included free for the lifetime of the kit.

Yes. The licence permits unlimited personal and commercial use, including SaaS products, client work, and projects you sell or monetise. The only thing you cannot do is repackage a kit unchanged and resell it as a competing template. If you build a product with it, ship it — that is exactly what these kits are for.

Next.js 15 with App Router, TypeScript, Tailwind CSS, and Prisma as the baseline across every kit. Auth uses NextAuth or Clerk depending on the kit. Payments use Stripe with webhook signing. UI uses shadcn/ui components. Validation uses Zod. Each kit is deploy-ready for Vercel, Cloudflare Pages, and Docker — no vendor lock-in.

They are genuinely free, with no signup, no API key, no rate limit, and no data sent to a server — every tool runs entirely in your browser. We built them because we use them ourselves between commits. The marketplace exists to fund the time spent maintaining them, but the tools themselves are not a funnel — use them without ever buying a kit and that is fine by us.

Yes. Every kit ships with lifetime updates for the major version you bought. When we patch security issues, bump dependencies, or add features to a kit, you get access to the new version at no extra cost. You will receive an email when there is a meaningful update, with a changelog of what changed and any migration notes.

Fourteen days, no questions asked. If a kit does not fit your needs — for any reason — email support@devkitmarket.com within 14 days of purchase and we refund in full. We would rather refund than have you stuck with code you are not happy with.

Immediately after checkout you receive an email with a download link and, where applicable, an invite to the private GitHub repository for the kit. You can re-download from your account at any time and pull updates directly from the repo. There is no DRM, no licence server, and no activation step — once it is on your machine, it is yours.
